What? No delete event in Liferay Social Office?

A strange thing indeed, for some company to release a beta software which is not functionally complete. I always thought that a beta software is fully functional but without a production-grade stability. Of course, the software industry has its historical anti-example such as QuarkXpress (3.3 or 4, I forgot) which had an alpha release, beta release, and gamma release, before the true 'Release'.
Liferay Social Office is a simplification of Liferay Portal, configured for optimum social interaction, and in my opinion, knowledge sharing and management. What they really do is rewrite some GUI codes so the resulting UI is not too complicated to master. But here lies the catch. You could create a new Calendar Event, but there is no user interface from where you could delete the event.
Someone posted the question to Liferay's forums, and the question was answered with something like

.. er.. we would include the delete functionality in the next release ..

That is not an acceptable answer for me, because we were trying to use this Social Office for one of our client departments. So, for the meantime, I must be content with adding these lines :

<c:if test="<%= CalEventPermission.contains(permissionChecker, event, ActionKeys.DELETE) %>">
<portlet:actionURL windowState="<%= WindowState.MAXIMIZED.toString() %>" var="deleteURL">
<portlet:param name="struts_action" value="/calendar/edit_event" />
<portlet:param name="<%= Constants.CMD %>" value="<%= Constants.DELETE %>" />
<portlet:param name="redirect" value="<%= redirect %>" />
<portlet:param name="eventId" value="<%= String.valueOf(event.getEventId()) %>" />
</portlet:actionURL>
<liferay-ui:icon-delete url="<%= deleteURL %>" />
</c:if>

into the webapps/ROOT/html/portlet/calendar/view_event.jsp.
